Product Description: Protonstatin-1 is a selective plasma membrane (PM) H+-ATPase inhibitor (IC50 of 3.9 μM) that inhibits auxin transport. Protonstatin-1 interacts with the PM H+-ATPase central loop and may thus impede the functions of the N- and/or P-domain to inhibit the pump activity[1][2].
Formula: C8H5NO2S2
